    Description

      Our default configuration is not using the server mode and therefore if one tries to initiate a backup call via CLI or REST, it will be failing due to the fact that h2 is not allowing more than one connection at a time.
      Before we didn't have this issue in Magnolia but for some reason (most likely h2 or jackrabbit updates) we have it now. A potential workaround is to run H2 in server mode and hence more than one connection to the DB is allowed.
